No. Not getting caught is no excuse for breaking the law again. If you were speeding and got caught, then you deserve the punishment.

Sorry, that won't hold up. Next time you see the cop approaching, you could *try* putting on your lights and siren. This is probably illegal but then again, so is speeding. I wouldn't do it, but I'm not particularly brave.

If the speed is presumed, and not posted as a limit. You may ask the jury to decide if your speed of travel was justified considering your back ground as an official of the county you are employed. (Don't take it before a judge, his job is like the cops, to make the county money by finding you guilty. Request the jury to decide punishment if found guilty, they are more sympathetic than a judge) The problem here resides in the amount of the fine, here in TX I believe that the fine is $10 or $20 for every MPH you travel over the speed limit. If the limit is presumed, how is one to know how fast to travel, safely? Sounds like a speed trap, im sure many jury members have also found themselves in your predicament as well. There is also the flow of traffic. Were you the only vehicle traveling on the road at the time? Or were you proceeding with the flow of traffic? Even if your the only one on the road, your vehicle can be referred to as that vehicle which has set the flow of traffic. Thusly you felt it safe to travel at the speed you were traveling at that time, on a presumed speed road. As a paramedic, you are a highly trained professional driver, and a professional driver is a defined as a safe driver.

No there is no excuse, unless you were on duty. Whether you are a medic, doctor etc, speeding deserves a citation. I would not mention to the judge that you usually drive that same speed, or they will nail you again and again.
